Innomar "medium-usv" SBP fur USV integration

Innomar standard parametric sub-bottom profiler (top side unit) The Innomar medium-usv model performs like an Innomar medium-100 SBP and is intended to be used on uncrewed surface vehicles (USV / ASV).

The high ping rate, a small footprint and the possibility of transmitting sound pulses over a wide frequency range ensure sub-bottom data with excellent resolution and very good sediment penetration. Electronic beam stabilization across (roll) or along track (pitch) is used to compensate for wave-induced vehicle movements.

A user-friendly Windows data acquisition and system control software (SESWIN) is used for remote (Ethernet) operation. The Innomar medium-usv model acquires full-waveform data that can be processed with any seismic software (SEG-Y format). Innomar also provides the ISE post-processing software specialized on the Innomar SBP data.

This model has been launched in 2020.
